RAILROAD-CROSSING.

Patented Nov. 13, 19062 Application led June 7,1906. Serial No. 320.596.

To all whom t may concern:

Be it known that I, HORACE A. BAKER, a citizen of the United States,residing at Pecan Gap, in-the county of Delta and State of Texas, haveinvented certain new and useful Improvements in Railroad-Crossings; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to Which itappertains to make and use the same.

My invention relates to improvements in railroad-crossings, and moreparticularly to a derailing mechanism, by means of which liability ofcollision will be reduced to a minimum.

The object of the invention is to provide a derailing mechanism of thischaracter which will be of simple and comparatively inexpensiveconstruction and veryeifective 1n operation.

With the above and other objects in view the invention consists in theconstruction, combination, and arrangement of devices hereinafterdescribed and claimed.

In the accompanying drawings, Figure 1 is a plan view of arailway-crossing having my improved derailing mechanism applied there-'to. Fi 2 is a detail view, on an enlarged scale, o one of the derailingdevices and its connected parts. Fig. 3 is a longitudinal sectional viewtaken on the lane indicated by the line 3 3 in Fig. 2. 4 is a detailsectional view taken on the ane indicated by the line 4 4 in Fig. 2, andFig. 5 is a detail sectional view taken on the plane indicated by theline 5 5in Fig, 1.

Referring to the drawings by numerals, 1 and 2 denote two intersectingrailroad-tracks upon which my im roved derailing mechanism is mounted.his mechanism comprises four derailing-blocks or devices 3, located atsuitable distances from the intersection of the track-rails, and onebeing provided for each of the four branches of the crossin Each of thederailing blocks 3 is carried xClhy a transversely-sliding bar 4, whichhas its opposite ends connected by links 5 to angle-levers, bell-cranks,or the like 6, which are mounted upon vertical pivots 7, located uponthe opposite sides of the tracks. Mounted in suitable bearings ad'acentto the sliding bar 4 upon each of the ranches of the intersecting tracks2 are transversely-extending shafts 8,

which have upon their projecting ends wheels or thelike 9. Each of theshafts Sis rocked or oscillated by means of a push-b ar 10, located uponone side ofr one of the track-rails "and adapted to be depressed by theflanges'of the4 wheels of a car or trainpassing over the same.

Each of these bars has one of its ends pivotally' connected to acrank-arm 11 upon the adjad cent shaft 8 and its other end pivotallycon' nected to a similar cranksarm 12, suitably mounted u on one of thecross-ties or upon onef of the trac rails The crank-arms are equal inlength, so that the bar 10 will be maintained in a horizontal plane asvit swings vertically. Suitable springs 13 are provided for mai-nwtaining the bars 10 in their elevated positions,

so that when the flanges of the car-wheels strike their rounded endsthey will be forced -downwardly against the tension of said springs torock the shafts 8 and partiallyro -1 tate the Wheels; 9. Each of thewheels 9 is connectedby a cable or other flexible-connection 14 to oneof the rotary disks 6 uon the-- adjacent side of one of the branches othe intersecting track, so-that when. the shaft 8 upon one Abranch ofone of the tracks is actuated its motion will be imparted through s aidconnecting-cables to the two rotary disks.

upon the adjacent sides ofthe two branches of the other or intersectingtrack, in order that the two disks thus actuated will shift thederailing-blocks, which they control, from an inoperative to anoperative position. Thus as a car or train approaches a crossin upon oneof the tracks and actuates the ar 10 upon that branch of said track thetWo derailing blocks upon the branches of the other or intersecting.track will be moved from an inoperative to an operative position inorder that trains approaching the crossing in either direction upon thelast-mentioned or intersecting track will be derailed before they reachthe crossing.

' Each of the cables 14 has one of its ends secured to and wound uponone of the wheels 9 corners of the crossing, and they are protect- IOO I.intersecting track to'be moved into an operative position, so that atrain or trains u on said intersecting track will be derailed be orereaching the crossing.

Any suitable electric or other si naling device may be used inconnection-with this de- `railing mechanism, so .that engineers uponapproaching trains will be warned of the danger ahead before they reachthe derailing devices.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to Without departing from the principle orsacrificing any of the advantages of the invention as defined by theappended claims.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1.- The combination of intersecting tracks, a transverselyamovable baron one of said tracks at a distance from the crossing andhaving aderailing-block, a rotary element mounted near said bar and connectedthereto, a rock-shaft mounted on the other track at a distance from thecrossing and having awheel and a crank-arm, anoperating connectingelement between said wheel and the said rotary element to actuate thelatter and the said bar and derailing-block, and a train-operatedpush-bar connected to the said crank to operate the same, for thepurpose set forth.

2. The combination with intersecting tracks, of transversely-movablebars located u on the branches of said`tracks, derailingb ocks carriedby said bars and movable toward and from the rails of said tracks, rockshafts located in the branches of said intersecting tracks, atrain-operated device upon each branch of said intersecting tracks, eachof said devices actuating the adjacent rockshaft, rotary elements foractuating said derailing-block-carrying bars, and connections betweensaid elements and said rock-shafts, substantially as described.

3. The combination with tracks, of transversel -slidable bars upon thebranches of said trac s, derailing-blocks carried by said bars andmovable toward and from the rails of said tracks, rotary elementsforzactuating said sliding -bars, rock-shafts located in the branches ofsaid tracks, ushbars located adjacent to the rails o the branches ofsaid tracks for operation by the car-Wheels of passing trains,connections between said bars and said rock-shafts, guides, and flexibleconnections engaged with said guides and connected to said rock-shaftsand said rotary elements, substantially as shown and described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
